Specification of Letters ZPatcnt.

Application filed Apriz 8Q, 1914. Serial lie.

To all whom it m an concern Be it known that 1, WILLIAM S. Rawson, a citizen of the United States, anda resident of East Orange, county of Essex, of New Jersey, haveinvented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

This invention relates to an improved window and is adapted for use in windows which have a sash that is adapted to be low ered into a well when opened and raised when closed, this type of window being particularly desirable in carriages, automobiles and the like.

The invention relates particularly to an inconspicuous means for raising and lowering the sash, the said means: being adapted to hang within the well, when it is not being actually used to slide the window, whet-her the window is open or closed.

The invention is further designed toprovide means for automatically holding the sash at various heights when the means for raising and lowering the sash is not so employed. The automatic holding device or '4 s latch is operative as a support when the h 7 ing means 1s inoperative, the latch for hold to suspend the sash.

ing the sash also acting from the lifting means and thereby role the latch from the element which supports when the height at which the sash is held to be changed.

Another feature of the invention is the latch by means of which the sash is raised, lowered or held in place, the latch being simple and easy of operation, its simplicity making the successful operation of it assured.

'The invention is also designed to provide a latch constructed to engage a supporting strip, such as a rack, chain or the like, the latch when in operative connection with the strip holding the sash against downward movement and so transmitting the weight of the sash to the supporting strip so that the strip is not forced in a transverse direction so that the panels or other parts of the side walls of the well are not forced outward by the strain. The latch is constructed so that it is operated easily, being forced to open position by the lifting strap or string and the weight; of the sash having a tendency to move upward and downward respectively and swing the latch from its engagement with thesupp n and State,

he r reference a windo in to show the in being broken away is side view of Fig. that a: broken away in Fig. in section in Fig. 2. Fig. 3 i a front of the latch on a larger scale. Fig. 4 is section on line a, at, in Fig. 3. Fig. 5 is a top view of the swi ing portion of the latch. Fig. 6 is a detail of iatcli.

in the embodiment of invention illustrated in the drawing the window consists of a frame 10 which is illustrated as of the usual form and" dimensions as employed in doors and windows of au'tcinbbiles, carriages and the like vehicles, althfiugh it will be understood. that the invention is adapted to be used in any situation where it is applicable. The frame as shown comprises a top rail 11, side rails 12, one of which is shown, and the bottom rail 13, the lower portion of the frame forming a well, since the side panels Hand the side strips 15 and 16 inclose this portion of the frame. This structure, of course, is subject to such changes as are necessary for ornamentation which may be necessary in view of the situation of the frame. Sliding in the frame is a sash, and the sash can he of any type, either the ordinary sash inclosing a pane of glass or the like, or it may be as is illus trated in the drawing which illustrates the sash consisting of a glass pane-17 along; the bottom edgeof which is a strip 18, this structure being called the in this specification for the purpose identification.

i 1 bei i g: movement, revel of the I the well. by j on the side mes l2, and

passes upward so as to proformed in the upper nc, above the side strips -d by sultable guides 20, ally pivoted near their top so that when the sash is up position, it can he held in such of hooked portion 22 ill, the hook 22 resting on n; manner of supportadow at its top point is common 3 his kind, and in the coach. e-malzers trade it is known as h 'iiunp the fence, since a an nent of the guides isi 2o the ttom edge of the guides to he toward the rib and the sash is ed to have an excess movement upas to permit its being jumped over it will be understood, how- :Ze t otaer loeans may bev en'iployed for sash in its closed position.

of this kind the sash lifted from so tom, and this has been done by a device known in the trade as a string,

inc" 0v i sash closed.

'n mv con l the well c on the strap drops down except for its handle at the and irrespective of the height which window is held. the old type of sliding; window the sash is held at an intermethe diate point button-hole in the strap being passed over a stud or button on the inside of the door, or by an equivalent fasteningz, all this however providing for the end of the strap hanging, over on the inside of the door, in addition to its being in the way, it

ance.

In the construction shown I manipulate the sash by means of a strap 24 which has a handle 25 on its top end, the preferred form of handle being described hereinafter, but any suitable handle can be employed so long it limits the movement of the s rap in the well. The strap is normally, su pended in the well and is freely slid-able therein, being limit. l, however, in its upward movement relative the sash by a suitable stop. This stop is shown in the 0 term illustrated as a. metallic or similar bar 26 projecting om the sides of the strap toward its hot an em, being adapted to act as limit for tee upward movement of the strap relative to the sash, this being usuall provided for by passing the strap leased and vice versa.

does not maize a good'appear through a slot 27 in the plate 28 which is fastened to the sash. It will thus be seen that wish the strap is pulled up until the stop 26 engages the plate 28, and then is further pulled upward, the sash will be pulled upward with it, and it will also be noted that when the sash is held at any ieight by means other than the strap, the strap is free to retreat either by gravity or any other force and automatically assume a position suspended within the well, as shown in Figs. 1 andQ. In this manner the strap, except when it is heing actually employed in controlling the sliding of the sash, is out of sight except for its handle, and the appearance of the door or other form of frame is not marred by the presence of an overhanging end and the strip is not in the way,

in conjunction with the strap 1 have devised means for holding the sash at various points in its path of travel, and'l prefer to form this holding means in the form of latch which is operated to engage a suitable support and is also operated to release the sash from the support, but I prefer to combine the strap and the latch so that when. the strap supports the sash, the latch is re- When the strap is not supporting the sash the latch is permitted to become operative against the support and the strap is free to retreat Within the well. The preferred form of latch is -illustrated in Figs. 1, 2, 3, l and 5 of the drawing, the latching means comprising a latch 29 having the operating plate 28 projecting from the front of it, the latchbepivoted to the lower part of the sash, this being usually done by means of knuckles 31 swinging on a pintle 32 which also passes through the knuckles 33 of a plate 34 fastened to the bottom part of the sash. The plate is bent on its front side into a stop 35 which limits the upward swing of the latch-plate toward the sash on the side of the support. The latch, on its projecting end, is provided with means for engaging a supporting strip, the supporting strip being in the form of a rack or chain, or other similar structure, the preferred form, however, being shown as a rack 36 having the teeth 3'? which are so disposed that they form recesses 38 between them, these recesses being adapted to receive a short bar 39 on the end of the latch, the bar forming part of the latch and being preferably provided with a covering 40 which may be of rubber or the like to prevent the clicking which is the result if a metallic latch were passed over the teeth 37.

W hen the pane 17, or any other form of sash, rests on the latch, the latch-plate 29 is forced up against the stop 35 and supports the sash on the rack by means of its bar 39, the parts being so disposed that the latchthe strain on the recesses 38 is downward and not sidewise, and there is no tendency of the weight of the sash pushing the rack outward and forcing it agains the paneling or i any other ornamental covering of the well. In other words, the strain on the supporting stri such as the rack, is longitudialong said strip. The releasing plate 28 is provided with a slot 2? through which, previously described, the strap 2% is adapted to freely slide.

When the sash is at its hot-torn point or is as far down in the well as it will go, it usually rests on a block ll which is arranged at the required height and acts as a cushion to support the sash at its lowest point and to also eliminate any noise of contact when the sash is lowered onto the block 41. when the sash is at its lowest point it can be raised in two ways. First, it can be grasped at its top edge and pulled upward as high as desired, the upward movement of the sash not ail'ecting the strap, since the strap slides freely in the slot 27, but the latch up over thcjeeth 3?, this passage besuostantially noiseless on account oithe soft covering 40 of the latch bar 39. When the sash is at the required height it is pre- -1 l-e do a RH f h erase irom esccncing y reason 0 b e latch being forced against the supporting strip by the spring 4-2 or any other suitable for normally forcing the latch in means contact with the supporting strip. The

' other manner of raising the sash is by pulling on the handle 25 which pulls the strap 2 upward, the stop 26 engages the bottom side of the plate which forms a releasing late, and the strap thus overcomes the ressure spring as and swings the .atch up to the position shown in dotted outline in ig. l, thus releasing the latch from its contact with the supporting strip,

and she sash can be freely slid to any point up or down by means of the strap. "W hen the sash is to be secured at anyheight it is, either supported by one hand while the strap is released and allowed to fall within the well, after which any release of the sash will force its latch to support it, or the strap can be given a jerk when the sash is at the required height. This upward jerk serves to permit the sash to force the latch in engagement with the strip at the instant following the jerk when the release of the strap irom the sash gives the spring 42 a momentary chance to swing the latch into engagement with the supporting strip. Whenever the sash is in the desired place it is under- 1 stood that the strap 24 can retreat and assume its normal position illustrated in Fig. 1. The handle, at the top end of the strap is usually arranged to serve as a stop'to limit the descent of the strap, and the preferred form of handle in the form of a cylindrical grip 25 which is thick enough to prevent its passing between the glass of the window and the top edge of the well so that it is always in position to be grasped. This form of handle is not conspicuous and is usually provided with soft hands 51, such as rubber or felt, so as to prevent any rattling when used on a vehicle.

In Fig. 6 1 illustrate a modified form of latch v'i'lllll is constructed to engage opposite sides of the supporting strip. The device as shown is secured to the bottom rail 18 of the sash and consists of pivoted teeth 51 normally pressed inward by suitable springs 52 so that these teeth normally on gage suitable. recesses 53 in the supporting strip 54. In order to release thelatch l provide the teeth with levers 55 having studs 56 on them, the studs 56 being in the path of the stops 26 of the strap 2%. Suitable studs 57 are disposed so as to limit the swing of the lovers 55 and engage them so that the sash can be lifted by the stops 26 engaging the studs 56 on the levers 55.
